Add perplexity; resolves #35

[seanoliver]

@swyxio Nearly there with perplexity but for some reason I can't get the submit to work yet

[swyxio]

var nativeTextAreaValueSetter = Object.getOwnPropertyDescriptor(window.HTMLTextAreaElement.prototype, "value").set;
nativeTextAreaValueSetter.call(inputElement, 'This should be in state');

const event = new Event('input', { bubbles: true});
inputElement.dispatchEvent(event);
